IMPROVEMENT IN GAS' APPARATUS.

Specification forming part of Letters Patent No. 203,909, dated May 21,1878; application filed March 8, 1878.

To an whom it may concern:

Be it known that I, J OHN HANLON, of the city of New York, have inventedcertain newand useful Improvements in Gas Apparatus, of which thefollowing is a clear, full, and exact description, reference being hadto the accompanying drawings, making a part of this specification, inwhich-- Figure l is a perspective view of a gas apparatus with myimprovements attached. Fig. 2 is a rear view of the same. Fig. 3 is aplan view with the cover removed, Fig. 4 is a longitudinal verticalsection through as m. Fig. 5 isa longitudinal vertical section through yy. Fig. 6 is a cross vertical section through 2 c. Fig. 7 is ahorizontal section, showing grate-bars.

My invention relates to that class of apparatus used for the manufactureof gas from petroleum; and it consists in the several combinations ofdevices hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I willproceed to describe the exact manner in which I have-carried it out. 1

In the drawings, A represents the shell or outside boxing of myretort-bench; B, the furnace; O, the ash-pit; D D, the central retortsor superheaters; D, the side retorts; and E E, the superheating steamchambers. The fire-grate F is composed of the boiler-tubes f, whichconnect at each end with common pipes G, which secure a free circulationof Water through all the tubes forming the fire-grate.

The flame and hot products of combustion from the furnace B are notallowed to strike directly upon the retorts, but pass from the rear ofthe furnace, through openings H and the return side fines I, to thefront, and then,

through similar openings, enter the hot-air.

chamber J, enveloping the retorts and superheaters, finally passing offthrough the flue K and chimney L.

M represents the water-feed pipes, these pipes leading to the rear ofthe fire-grate, and there connecting with the pipe G and supplying theboiler-tubesf. The steam generated in these tubes rises through thepipes N to the superheater E, and, passing through E, returns to thefront through E, where the dry steam is discharged through the pipe 0into" the retort D at an angle with the oil-pipe, for a purposehereinafter explained.

I represents the oil feed pipes, through which the oil passes to theretort D, in which the oil is partially decomposed.

As the oil passes into the retort, and at the very point of entrance, itis struck at an angle by. the steam entering through the pipe 0. (SeeFig. 5.) By this manner of admitting the superheated steam and oil intothe retort D the heavy sluggish oil is driven forward through theretort, and no tarry matter is allowed to collect at or near the port.

After the oil has been partially decomposed in the retort D it passes,in a quasi-gaseous condition, through pipes Q at the rear into thecentral retort or superheater D, thence through this retort to the frontof the bench, and through outside passage R down into the retort D, andfrom this retort the gas passes through proper openings in the rear ofthe bench to the gasometer or receiver.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The retorts D, in combination with the upper retort D, connected bythe pipes Q, and with the lower retort D, connected by the outside pipeR, all constructed and relatively arranged substantially as and for thepurpose set forth.

2. The retorts D, D, and D and pipes Q and It, constructed and arrangedasdescribed, in combination with the steam-superheaters E E and thepipes O and P, substantially as and for the purpose set forth.

3. The horizontal-center flue K, between the upper and lower retorts DD, communicating by suitable openings with the hot-air chamber J, incombination with the horizontal side flues I, connecting with the rearof the fire-box by the passages H, constructed as described.
